来自自然历史和调查收集的遗留生物多样性数据正迅速以一种通用格式在因特网上提供。全球生物多样性信息基金(GBIF)已经提供了超过1.1亿条记录。然而，我们有效利用这些信息进行生态研究、管理和保护的能力落后。一种解决方案是基于Web的地理信息系统，用于实现对这一快速增长的数据资源的可视化和分析。本文详细介绍了一个为部署在分布式数据库门户上而开发的案例研究系统--GBIF地图和分析门户应用程序(MAPA)。建立这样一个系统需要克服一系列技术和研究挑战。这些挑战包括：确保快速访问通过这些分布式生物多样性数据库可获得的海量数据；开发基于开放标准的访问适当环境数据层的方法，以分析生物多样性的分布；建立适当灵活和直观的地图界面，以完善分析的范围和标准；建立对生态社区至关重要的适当的基于网络服务的分析工具，并显示在线生物多样性GBIF数据的价值。在讨论了如何克服这些挑战之后，我们提供了案例研究，展示了使用GBIF-MAPA分析工具的两个例子。(C)2007 Elsevier B.V.保留所有权利。
Legacy biodiversity data from natural history and survey collections are rapidly becoming available in a common format over the Internet. Over 110 million records are already being served from the Global Biodiversity Information Facility (GBIF). However, our ability to use this information effectively for ecological research, management and conservation lags behind. A solution is a web-based Geographic Information System for enabling visualization and analysis of this rapidly expanding data resource. In this paper we detail a case study system, GBIF Mapping and Analysis Portal Application (MAPA), developed for deployment at distributed database portals. Building such a system requires overcoming a series of technical and research challenges. These challenges include: assuring fast speed of access to the vast amounts of data available through these distributed biodiversity databases; developing open standards based access to suitable environmental data layers for analyzing biodiversity distribution; building suitably flexible and intuitive map interfaces for refining the scope and criteria of an analysis; and building appropriate web-services based analysis tools that are of primary importance to the ecological community and make manifest the value of online biodiversity GBIF data. After discussing how we overcome these challenges, we provide case studies showing two examples of the use of GBIF-MAPA analysis tools. (c) 2007 Elsevier B.V. All rights reserved.
